Abstract: A large rectangular rotary table includes a fabricated tubular metal frame having top plates for supporting fixtures and large motor vehicle parts. A center portion of the table frame is supported by an annular turret bearing mounted on a base plate spaced above a floor plate by adjustable leveling screws. A drive unit is also supported by the base plate within the bearing and the center portion of the table frame and includes a planocentric gear reducer driven by an electric servo motor projecting above the table. A laterally projecting torque arm is mounted on the output of the gear reducer and is connected to the table frame by a sliding drive pin assembly which prevents radial loads on the gear reducer when the table is indexed. A fluid actuated table locating pin alternately engages a locating seat on each end of the table after the table is indexed.

Abstract: Horizontal guide rails are mounted on a base and receive linear bearings mounted on the bottom of a tower which carries vertical guide rails receiving linear bearings mounted on a vertical carriage plate. Linear bearings are mounted on the carriage plate and support a horizontal guide rail secured to a horizontal lift arm having an outer end portion supporting a precision locating pin device for a part. Separate gear belts extend around corresponding adjustable idler gears and drive gears and are clamped to the corresponding tower, carriage plate and lift arm. The drive gears are driven by corresponding drive units each including a reversible servo-controlled electric motor, a planetary gear reducer, an absolute resolver unit and an electrically actuated spring set brake. A plurality of the above apparatus are located on opposite sides of a linear part conveyor with the lift arms projecting inwardly in generally opposing relation.

Abstract: A pair of horizontally spaced and horizontally extending part support rails or elongated platens are each guided and supported for vertical movement by a pair of guide and support members having linear bearing blocks mounted on vertical guide rails attached to corresponding vertical housings. A bell crank is pivotally supported adjacent each housing and is pivotally connected to the corresponding bearing block by a first link member. Second and third link members pivotally connect each pair of bell cranks for each platen to each other and to a crank arm mounted on a horizontal crankshaft extending laterally below the platens. A combined electric motor and gear reducer have an output shaft coupled to one end portion of the crankshaft, and an electric brake unit is connected to the motor shaft. An overtravel arm is also secured to the output shaft of the gear reducer and actuates an overtravel switch connected to control the electric motor.

Abstract: A plurality of flat timing belts each has parallel spaced teeth, and opposite end portions of each belt are attached to a carriage by corresponding relatively adjustable clamping blocks and plates. The belts extend around a common drive sprocket on a drive shaft connected to a drive having a reversible electric motor. The belts also extend around corresponding tail sprockets on a tail shaft, and adjacent tail sprockets are free to rotate relative to each other. A clamping block for each belt is adjusted to obtain the same tension in all belts so that each belt may be operated at its full rated capacity. The belt drive system may be used for transferring or shuttling a plurality of tool trays laterally with respect to a working station at a conveyor assembly line and storage stations on opposite sides of the working station.

One of the clamping blocks for each belt is adjusted relative to the platform and the other clamping block for the belt to obtain the same tension in all belts so that each belt may be operated at its full rated capacity.

Abstract: A hub member receives a tapered collect for gripping a drive shaft such as a shaft projecting from an electric motor. The hub member extends into a surrounding cylindrical housing which is secured to rotate with the hub member and carries a set of generally square clutch plates. An annular drive member is supported for relative rotation by the hub member and has an inner portion projecting into the housing to support a set of annular clutch disks which interfit between the clutch plates. The housing encloses oil which circulates between the clutch plates and disks, and a set of rotary seals confine the oil within the housing while providing for rotation of the drive member relative to the hub member and housing.

Abstract: A tubular hub member receives a shaft and is surrounded by a housing formed by a base section coupled to a cup-shaped closure section. The hub member defines an inlet passage for circulating cooling oil and supports a set of brake discs which interfit between a set of brake plates supported by pins projecting inwardly from the base section. An annular thrust plate is supported by the base section for axial movement and carries a set of compression springs which urge the thrust plate for clamping the brake plates and discs against a pressure plate mounted within the closure section. An annular electrical coil and support body are mounted by screws and spacer sleeves within the closure section, and an annular armature plate is supported by the sleeves for axial movement adjacent the end wall of the closure section.

Abstract: An oil shear clutch-brake unit includes a housing rotatably supporting an input shaft and an output shaft in axial alignment, and the housing encloses a set of interfitting clutch plates and discs for coupling the input shaft to the output shaft and a set of interfitting brake plates and discs for braking the output shaft. A non-rotating actuating member or piston is also enclosed within the housing and is actuated from a neutral position by springs and/or fluid for either clamping the clutch plates and discs or clamping the brake plates and discs. A cooling and lubricating oil is circulated within the housing and between the plates and discs, and the pressure of the fluid for actuating the piston is adjustable for selecting the torque transmitted through the clutch and brake.
